* [HTML_LIST,EXT] Adaptations for the web_modules/1 alterations.
* [RDF_WEB,EXT] Reimplemented HTML form for new CSS rules.
* [WEB_COMMANDS,FIX] The HTML for help_web/1 was not displayed correctly under the new CSS rules. Removed empty sublists in order to fix this.
* [WEB_CONSOLE,EXT] Minor adaptations to work with new CSS rules.
* [WEB_MODULES,EXT] Reimplemented web_modules/1, returning list-based triples now.
* [WEB_MODULES,FIX] web_module/3 was not nondet due to mutex.
* [DCG_GENERIC,SC] Renamed dcg_trace//0.
* [RDF_MAT,EXT] Allow non-list input for regimes parameter (put into a singleton list).
